How to Install a Garbage Disposal

No kitchen is complete without a garbage disposal. You won’t know how much you need one until you don’t have one. If your kitchen sink doesn’t have a garbage disposal installed in it right now, this post will help explain the process. This is an easy home repair project that will really help you when your are in your kitchen.

Do You Have An Electrical Outlet?

The first thing you need to do is ensure there is an outlet and switch near the kitchen sink. Garbage disposals run on electricity. If you do not see an outlet near or underneath the sink then you will need to call a local electrician and have them install the proper outlet and switch before installation of a garbage disposal can occur.

You also need to see if a permit is required for the installation. You can do this online or research your local .gov site for more information.

Garbage disposals are available in 1/3 up to one horsepower. Each garbage disposal manufacturer will provide information on how much power you need for your use of their product. Your home kitchen shouldn’t require the most powerful model available.

Time to Install!

Now it is time for the installation. The first thing you need to do is find your circuit box and turn off the power in your kitchen. Since there is electrical work required in this project you need to be very careful about the power.

Now disconnect the drain pipes beneath the sink and position a bucket under the pipes for water that runs out. Then you can remove the sink strainer that is currently in the sink basin where you want the garbage disposal and remove the adhesive or putty that fastened the strainer.

Now apply plumbers putty along the flange of the new drain and push it into place in the bottom of the sink basin. Place a towel in the sink basin over the new drain and sit the garbage disposal on top of the towel to help the drain set in place and prevent it from shifting during the installation.

Now stack the fiber gasket, backup flange and mounting ring and slide them on the underside of the flange underneath the sink. Then install the snap ring around the bottom of the flange. Now tighten the screws for a firm seal.

Now remove the electric wire plate and connect the electrical wire cord by marrying the two cords together. Attach matching wire colors together and push them back in and reattach the plate.

Time to Connect!

To connect the drain, insert the gasket in the discharge outlet then attach the discharge tube with a flange and bolts. Now hang the disposal by aligning the three tabs with the mounting ring. Then attach with the tabs and tool provided by the manufacturer.

Then connect the dishwasher drain and line up the discharge pipe. Test the connection by placing the stopper and see if the water sits. If the water sits there are no leaks in your seals.

Then you can plug in the garbage disposal and turn the power back on in your kitchen. Flip on the garbage disposal switch and see if it works properly. If it does, the project is complete!
